John Venn: A Circular Mind

Today was born John Venn,
One of those mathematically brilliant men.
Sorting apples from oranges, jellies from jams
Is more easily done with his diagrams.*

  • I was not as aware of Venn himself as the concept, which was well explained in high school in the sense of subsets. Pat Nixon (Madeline Kahn) illustrated it well in the Saturday Night Live sketch on the final days. Too bad that one of the authors of the sketch is now a U.S. Senator.
